Detailed Description
The WaylandSeat type provides access to different types of user input and maintains a keyboard focus and a mouse pointer. It corresponds to the wl_seat interface in the Wayland protocol.
Signal Documentation
This signal is emitted when the client has requested for a specific surface to be the mouse cursor. For example, when the user hovers over a particular surface, and you want the cursor to change into a resize arrow.
Both hotspotX and hotspotY are offsets from the top-left of a pointer surface, where a click should happen. For example, if the requested cursor surface is an arrow, the parameters indicate where the arrow's tip is, on that surface.
Note: The corresponding handler is onCursorSurfaceRequest
.
void keyboardFocusChanged(QWaylandSurface newFocus, QWaylandSurface oldFocus) |
This signal is emitted when setKeyboardFocus() is called or when a WaylandQuickItem has focus and the user starts pressing keys.
newFocus has the surface that received keyboard focus; or nullptr
if no surface has focus. oldFocus has the surface that lost keyboard focus; or nullptr
if no surface had focus.
Note: The corresponding handler is onKeyboardFocusChanged
.
Method Documentation
Sends a key press (if pressed is true
) or release (if pressed is false
) event of a key qtKey to the keyboard device.
void sendTouchCancelEvent(WaylandClient client) |
Sends a cancel event to the touch device of a client.
void sendTouchFrameEvent(WaylandClient client) |
Sends a frame event to the touch device of a client to indicate the end of a series of touch up, down, and motion events.
void sendTouchPointMoved(WaylandSurface surface, int id, point position) |
Sends a touch moved event for the touch point id on surface with position position.
Note: You need to send a touch frame event when you are done sending touch events.
Warning: This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled, as it might lead to conflicting touch ids.
Returns the serial for the touch motion event.
uint sendTouchPointPressed(WaylandSurface surface, int id, point position) |
Sends a touch pressed event for the touch point id on surface with position position.
Note: You need to send a touch frame event when you are done sending touch events.
Warning: This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled, as it might lead to conflicting touch ids.
Returns the serial for the touch down event.
void sendTouchPointReleased(WaylandSurface surface, int id, point position) |
Sends a touch released event for the touch point id on surface with position position.
Note: You need to send a touch frame event when you are done sending touch events.
Warning: This API should not be used in combination with forwarding of touch events using WaylandQuickItem::touchEventsEnabled, as it might lead to conflicting touch ids.
Returns the serial for the touch up event.

Sends a key press event of a UCS4 unicode through a text-input protocol.
Note: This function will not work properly if the client does not support the text-input protocol that the compositor supports.
This method was introduced in Qt 6.7.

Sends a key release event of a UCS4 unicode through a text-input protocol.
Note: This function will not work properly if the client does not support the text-input protocol that the compositor supports.
This method was introduced in Qt 6.7.
